An electrical diagram generally consists of a circuit diagram, a technical description and a title bar. ?
The circuit has two purposes: one is to transmit, distribute and convert electric energy; The second is to convey information.
Handle.
The contents involved in electrical construction drawings are often different according to the different functions of buildings, mainly including power supply and distribution, power and lighting, lightning protection and grounding, and weak current of buildings. , expressing different electrical design contents.
Construction drawing features:
(1) Building electrical engineering drawings are mostly drawn with unified graphic symbols and text symbols.
(2) All circuits must form a closed loop.
(3) All kinds of equipment and components in the line are connected into a whole through wires.
(4) When reading building electrical engineering drawings, you should read the corresponding civil engineering drawings and other installation engineering drawings to understand the coordination relationship between them.
(5) Building electrical engineering drawings often can't fully reflect the installation methods, quality requirements and technical requirements of equipment use and maintenance, so when looking at drawings, you should refer to relevant atlas and specifications.
